lThis invention relates to the class. of demountable vehicle rims and pertains particularly to a rim designed to be broken transverselyv to facilitate its-removal from and application to a tire. y y y l 1 The primary object ofthe pre-sent invention is to provide avehiclei tire rim which y can be easilyand'quickly distorted or broken to reduce the circumference thereof so that a vehicle tire can be placed thereon orl removedv therefrom with ease.

Another object of the invention is to pro-V y vide a vehicle tire rim which, yafter being broken and havinghad a tire placed thereon,

'can be restored. to normal` size and shape easily and quickly.v y

The invention will be best understood from l a consideration of the following detailed de scription taken 4in' connection with the ac companying drawings forming a part of the present specification, with the understanding, however, thatthe invention is not conlined to any strict conformity with the showing of the drawings, but may be changed or modified so long as such changes or modications marl; no material departure from the salient features of the invention as expressed in the appended claims.

In thel drawings: y i y Figure l shows the tire rim embodying the present invention, in side' elevation Figure 2Yis a section taken upon the line 2-2 of Fig. l. c

Figure 9 is an enlarged sectional view taken upon the line 3-3 of Fig.2.

Figure l is a detailed perspective view of one of the ends ofthe split rim showing the means provided forA the receptionof an engaging tongue carried by a removable vsection of the rim. l

Figure 5 is a detailedvperspective View of one endof one of the removable'rim sections which co-actswth the end shown in Fig. 4.

Figure 6 is a detailed perspective view ofl one'end of one of the movable rim sections n against which an end of an adjacent and'simi- ,'9 extends. 'Y

"i Figure 8 is a detailed perspective viewof l thev locking or coupling tongue which vis 'welded in theseatformed in 'the member shown in Figure l Y y Y Y l l Referring now 'tothe drawings in detail, wherein like numerals of -reference indicate corresponding parts throughout the. severall views, the numeral-1 indicates the major sec- Y 16o. tion' andl the numerals 2 andlthe inner see- 1 tions'of the rim whichV is of channel lfo'rmaf Y tion, the adjacentor abutting ends of the v sections 2 vand 3 being cut obliquelyyof the rim asin dicated-at 4t. yflherem,ote'ends 5 and G'of the' rim sections 2 and 8, respectively are each cutobliquely of the rim',al`so, as shown,v The ends of the section l and the remoteends of the`sections2 'and S-are arranged at acute angles 'with respectto the bottom walls of the sections 21and 3. The-ends 7 of thesec-4 ktion 1 which abut theangled ends 5 andlof againstfthe sections will have avtendency to tighten the'same in their respective positions. Y

, Thevinnerface of the section 1 adjacent each-end thereof is formed-to provide vrthe. re-y Vceiving pocket orrecess 8 for the reception of the engaging linger `9 carried by andextending from the central portion of the endv of the section-2 inthe manner as clearly shown Vin Fig, 3; An additional reinforcing ylug-1() isformed upon the inner face of the section l2 at'the inner end ofthe fin`ger9 and provided with a recess snugly receiving-beveled edge 'of ythe pocket 8 in vof the section yl isalso whichthe adjacent finger Boeket l1 designed to receive the ingermemer 12 carried upon the section-2.y The' secvtion 8 isv provided with alug similar tothe Y,

`mgt10, and Jphepocket 1.1 has -abeveld edge section the tongue hereinafter described,

carried by the adjacent section, engages.

The locking key or tongue which is "einployed to connect the sections 2 and 3, is shown in detail in Figure 8 and comprises an elongated member indicated as a whole by the numeral 15, which in turn is made up Of l a tongue portion 16 designed, to be positioned in the pocket 14 of the section 3, and welded thereto, and aj aw 17 formedv at one end of the tongue which jaw comprises a relatively llong inner lip 18` and short outer lip 19. When thelocking key or tongue is welded in position at the inner end of the section 3 and the sections 2` and 3 are to be placed in position to forni a complete rim, the inner lip 18 of the jaw 17 is extended through the slot 13 from the outside thereof and the outer ends of the sectionsare positioned in the main section offthe riin to engage in the pockets-8 and 11. TWhen in` position pressure is applied simultaneouslyV to the two engaging ends of the sections` 2 and 3 and the same forced outwardly apart causing the sections to assuine the position shown in Figure 3, the key 17 engaging under the bridge 13 at the inner end of the tongue portion 16. y

c From the foregoing it will be readily seen that a tire can be easily placedlupon the larger section ofthe rim after which the:v two sections 2 and 3 can ybe arranged inposition in the manner described, and pressed into place.

It will of course be readily understood that when it is desired to remove the tire.; from the rini a reversal of the foregoing operation is employed to produce the desired results.

Having thusdescribed our invention, what we claim is Ina deniountable rim of the character set forth, a pair of sections having abutting end portions, one section having avtransversely extending slot and the portion thereof adj acent the slot off-set inwardly to forrn a raised bridge, the other sectionl having a struck up pocketk an elongated tongue securedinsaid pocket and extending beyond the end j. portion of the last mentioned section in the saine plane as thesurface of thesection, theeuter end portion of the tongue being olf-set intongue will fit under the bridge and extend through said slot to lit upon the section adjacent the slot, while the lip engages the opposite surface of the saine section, as and for the purposes set forth.

In'testimony whereof We aflix our signatures. v f
